用粉末冶金法制备了ＳｉＣｐ／铝合金复合材料，并对其进行了力学性能测试和断裂特性分析；综述了用不同工艺生产的非连续增强ＭＭＣ的性能及影响因素；试图说明增强体／基体界面结合力是铝合金复合材料性能的控制因素；指出寻求适当的界面结合力是复合材料设计中的一个重要内容。 The SiCp / aluminum alloy composites were prepared by powder metallurgy method, and their mechanical properties and fracture properties were analyzed. The properties and influencing factors of discontinuous MMCs produced by different processes were reviewed. Binding force is the controlling factor of the properties of aluminum alloy composites. It is pointed out that it is an important content in the design of composite materials to find the appropriate interfacial bonding force.
